Yes. We've certainly experienced no safety issues operating on one in 50 versus one in 40. In fact, as we've stated before, it's quite easily an equivalent level of safety, and we see many benefits that provide extra safety barriers that we're watching.
As far as an international standard is concerned, when we reviewed, nothing pointed directly toward a concern around operating one in 50. As I said, it's the operational standard. When you look at the percentage of flights that operate under that regulatory jurisdiction versus in Canada or the United States, it far outweighs from that perspective.
